Description

Technical Field

[0001] This utility model relates to the field of paper processing equipment technology, specifically a paper perforation device. Background Technology

[0002] The preservation and archiving of paper documents requires binding, which is generally done using a binding machine. During the binding process, a hole punch is used to punch holes in the paper, followed by crimping or thread binding. Although our company's patented product (publication number CN111438755B) can solve the above problem, its application is limited; it can only punch holes in smaller sheets of paper, such as invoices. For thick and large documents, such as bidding documents, this product is essentially unable to punch holes smoothly. Utility Model Content

[0003] The purpose of this invention is to provide a paper perforation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a paper punching device, comprising a base plate and a pressure plate located above the base plate, wherein both ends of the base plate are provided with shaft pin seats, and both ends of the pressure plate are provided with threaded seats; a screw passes through the threaded seats and connects to the shaft pin seats, so that the pressure plate is moved by the rotation of the screw; the pressure plate is also provided with a punching assembly, the punching assembly including a bracket, a guide sleeve slidably mounted on the bracket, and a drill mounted at the bottom of the guide sleeve; by moving the pressure plate downward, the paper located on the base plate is pressed tightly, and by pressing the guide sleeve, the drill bit on the drill is moved downward to punch a hole in the paper.

[0005] As a preferred technical solution of this utility model: the guide sleeve passes through one end of the bracket and is connected to the pressure rod.

[0006] As a preferred technical solution of this utility model: a spring is also provided between the opposing surfaces of the pressure rod and the bracket, and the spring is sleeved on the outside of the guide sleeve.

[0007] As a preferred technical solution of this utility model: the pressure plate is further provided with a guide rail and a slider that slides on the guide rail, and one end of the bracket slides on the guide rail through the slider.

[0008] As a preferred technical solution of this utility model: both the base plate and the pressure plate are provided with waist-shaped grooves in the middle.

[0009] As a preferred technical solution of this utility model, the slider is also provided with a locking bolt.

[0010] As a preferred technical solution of this utility model: the screw is connected to a handwheel, and the screw is rotated by the handwheel.

[0011] The beneficial effects of this utility model by adopting the above technical solution are: 1. Since the base plate and the pressure plate are connected by a screw, the distance between the base plate and the pressure plate can be adjusted by rotating the screw, thereby enabling the device to clamp thicker paper;

[0012] 2. Because the screw causes the pressure plate to press the paper firmly onto the base plate, it can prevent the paper from shifting when the drill is making holes, thus ensuring the quality of the holes;

[0013] 3. Because the guide sleeve is manually controlled, the working status can be monitored in real time during drilling operations. If the drill bit malfunctions, adjustments can be made quickly to reduce the occurrence of drill bit breakage. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0020] Please see Figure 1-4 This utility model provides an embodiment of a paper punching device, comprising a base plate 1 and a pressure plate 4 located above the base plate 1. Both ends of the base plate 1 are provided with shaft pin seats 9, and both ends of the pressure plate 4 are provided with threaded seats 5. A screw 8 passes through the threaded seats 5 and connects to the shaft pin seats 9, so that the pressure plate 4 can be moved by the rotation of the screw 8. The pressure plate 4 is also provided with a punching assembly 3, which includes a bracket 30. A guide sleeve 33 is slidably mounted on the bracket 30, and a drill 34 is mounted at the bottom of the guide sleeve 33. By moving the pressure plate 4 downwards, the paper located on the base plate 1 is pressed tightly. Then, by pressing the guide sleeve 33, the drill bit on the drill 34 is moved downwards to punch a hole in the paper.

[0021] In summary, since the base plate 1 and the pressure plate 4 are connected by a screw 8, the distance between the base plate 1 and the pressure plate 4 can be adjusted by rotating the screw 8, allowing the device to clamp thicker paper. Simultaneously, because the screw 8 causes the pressure plate 4 to press the paper firmly onto the base plate 1, paper displacement during drilling is prevented, thus ensuring drilling quality. In particular, because the guide sleeve 33 is manually controlled, the working status can be monitored in real time during drilling operations, and adjustments can be made quickly if the drill bit malfunctions, reducing the risk of drill bit breakage.

[0022] To facilitate the user's application of force, the guide sleeve 33 passes through one end of the bracket 30 and is connected to the pressure rod 32; therefore, during use, the user can hold the pressure rod 32 to cause the guide sleeve 33 to drive the drilling rig 34 to move downward.

[0023] Meanwhile, since a spring 31 is provided between the opposing surfaces of the pressure rod 32 and the bracket 30, and the spring 31 is sleeved on the outside of the guide sleeve 33, the spring 31 can assist the user in moving the guide sleeve 33 upward after the external force disappears, so as to pull out the drill bit on the drilling machine 34.

[0024] Based on the above scheme, since the pressure plate 4 is also provided with a guide rail 6 and a slider 10 that slides on the guide rail 6, and one end of the bracket 30 slides on the guide rail 6 through the slider 10, the drilling machine 34 can make holes at different positions on the paper by moving the hole-making assembly 3. The guide rail 6 is symmetrically installed on the pressure plate 4, which makes the two ends of the hole-making assembly 3 evenly stressed and avoids the phenomenon of deviation during drilling.

[0025] Meanwhile, since both the base plate 1 and the pressure plate 4 have waist-shaped grooves 2 in the middle, the waist-shaped grooves 2 on the pressure plate 4 facilitate the contact between the drill bit and the paper, and the waist-shaped grooves 2 on the base plate 1 facilitate rapid free rotation after drilling, so as to avoid the problem of the drill bit directly contacting the table and damaging the table or the drill bit due to the user continuing to apply force.

[0026] Furthermore, since the slider 10 is also provided with a locking bolt 11, the slider 10 can be locked on the guide rail 6 by tightening the locking bolt 11, so as to further avoid the phenomenon of drilling deviation caused by the movement of the hole opening assembly 3 itself.

[0027] In addition, since the screw 8 is connected to the handwheel 7 and the screw 8 is rotated by the handwheel 7, it is convenient for the user to rotate the screw 8.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
